Abstract
The utility model relates to a closely coupled lead-acid accumulator, which comprises a housing. The housing is provided with a polar plate group, and a plastic polar plate bag of which the geometric configuration is identical with each polar plate and the left and the right sides are sealed is sheathed on the outside of the polar plate group. A positive and a negative terminals are arranged on both sides of a top cover, and when the accumulator is used in serial connection, the positive and the negative terminals of two adjacent accumulators can be connected through a screw bolt or a rivet, in order to overcome the problem that the internal resistance of the accumulator is raised caused by trans-line connection in the prior art.
Description
The utility model relates to a kind of storage battery, particularly a kind of tractor lead accumulator.
The tractor lead accumulator usually is in the operating state of deep discharge, comes off from grid in order to prevent active material, existing battery generally adopts sheath structure (document 1: volumes such as Wang Dezhi, " storage battery--principle and effect ", China Railway Press, P9-10,1989).Owing to adopt tubular structure, both positive and negative polarity group distance is far away, internal resistance is bigger during discharge, and in the use, Chang Yin has gathered pollutant and produced self discharge between positive and negative terminals, consume capacitance meaninglessly, in addition, plumbous utilance is low in the pond, so, above-mentioned tractor is low with the lead accumulator specific energy, but 20 KWh/Kg.Chinese patent application--" pocket type plate lead acid accumulator " (document 2: Chinese patent CN91202297.3) change pond inner anode plate into plate armature by original tubular structure, adopt plastics pocket type dividing plate and cancelled " saddle " of pond bottom land.Like this, not only can prevent the utmost point group short circuit that causes because of coming off of active material, and can avoid pole plate non-uniform corrosion, improved plumbous utilance.But, because the pole of this battery in the centre position of top cover, when the battery combination series connection is used, causes the internal resistance of cell to raise because of cross-line connects.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, proposes a kind of stressed joint formula lead accumulator, when series connection is used, does not need cross-line to connect, thereby has overcome the problem that the internal resistance of cell raises.
The utility model comprises a shell, disposes the common plane pole plate in the shell, and the outside of pole plate is with the plastic pad bag that the bottom identical with the pole plate geometry and the left and right sides all seal.The bottom inside of shell is the plane, and the pole plate group places on the bottom surface of shell, and positive and negative pole is arranged in the both sides of top cover, and when battery pack was connected, the positive and negative pole between adjacent cell was stressed joint.
In order to make the positive and negative pole between adjacent cell be stressed joint, can in the middle of positive and negative pole, make a call to a hole, connect by bolt or rivet therebetween.
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is that pole is arranged vertical view.
Fig. 3 is the pole connection diagram.
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are done detailed explanation.
With reference to Fig. 1,2,3, the utility model comprises a shell (3), the bottom inside of shell (3) is the plane, be placed with pole plate group (1) on it, pole plate group's (1) outside is with identical with the pole plate geometry plastic pad bag (2) that all seals with the left and right sides, and positive and negative pole (6,5) is arranged in the both sides of top cover (4).Have a hole in the middle of the positive and negative pole, connect by bolt (7) therebetween.
Do not connect owing to the utility model does not adopt cross-line, thereby overcome the problem that connects the internal resistance of cell rising that causes when series connection is used because of cross-line.
Claims (2)
1, stressed joint formula lead accumulator comprises a shell, and the bottom inside of shell is the plane, be placed with the pole plate group on it, pole plate group's outside is with identical with the pole plate geometry plastic pad bag that all seals with and arranged on left and right sides, it is characterized in that positive and negative pole is arranged in the both sides of top cover.
2, storage battery according to claim 1 is characterized in that, has a hole on the said positive and negative pole.
